Foodie Express is an exemplary ordering app that caters to individuals seeking a healthy eating lifestyle and those with food allergies. This app goes above and beyond by providing detailed ingredient information for each dish, ensuring that users can make informed decisions about their meals. By prioritizing the needs of users who have specific dietary requirements or allergies, Foodie Express promotes a safe and enjoyable dining experience.

In today's digital age, placing online orders for meals has become increasingly convenient. However, individuals with food allergies often encounter difficulties in finding suitable options that align with their dietary needs. As a UX designer, my role is to address this challenge by designing a food ordering app specifically tailored for people with food allergies. By providing detailed ingredient information, the app aims to empower users who prioritize healthy eating or have specific dietary restrictions.
Project duration:
November 2021 to April 2022

The problem:
People with food allergies have a difficult time placing an online order for their meals.

The goal:
Design an app that provides detailed ingredients for each dish to people who want to have a healthy eating style or/and have food allergies.

My role:
UX designer designing a food ordering app for people who has food allergies

To achieve this goal, I undertake various responsibilities throughout the design process. These include conducting user interviews to gather insights and understand the needs and expectations of the target user group. Additionally, I create both paper and digital wireframes to visualize the app's interface and structure. Through low and high-fidelity prototyping, I simulate the user experience and refine the app's functionality. Conducting usability studies allows me to test and validate the effectiveness and efficiency of the app's design. Moreover, I ensure accessibility considerations are accounted for, making the app inclusive for all users. Finally, I iterate on designs based on user feedback and continuously improve the app's usability and user experience.

User Research Summary
To gain a deep understanding of the users I am designing for, I conducted interviews and created empathy maps. Through this research, a primary user group emerged—users with multiple allergies who desire access to detailed ingredient information. These individuals are cautious about potential allergens and want to ensure the dishes they order won't trigger any allergic reactions.

Furthermore, users confirmed a common problem—most restaurants fail to provide comprehensive ingredient lists, even for dishes labeled as allergy-free. Hidden ingredients and insufficient transparency pose health risks for users when placing their orders. As a result, additional research and time are often required, making the ordering process more challenging for individuals with food allergies, particularly when ordering take-out.

By addressing these pain points and incorporating detailed ingredient information, the app I design aims to alleviate the difficulties faced by users with food allergies, ultimately enhancing their ordering experience and promoting their well-being.

Pain Points
Working classes are too busy to do additional research on all ingredients whenever they order take-out
No details information is provided to the users, which makes it difficult to avoid food allergies
The risk to trigger allergies remained high, as most restaurants are not able to provide ingredients from suppliers

Usability Study: Findings​​​​​​​
I conducted two rounds of usability studies. It was a valuable practice that can provide valuable guidance for refining my prototype and enhancing the user experience.
Round 1 findings
1. Icon is a bit confusing
2. Not sure where to find order status after exiting the app or screen
Round 2 findings
1. Users want to have the ability to undo actions in the cart

2. Users want to be able to edit the order

3. Additional way to add or remove items
The initial low-fidelity design provided valuable insights from usability studies, enabling adjustments and improvements based on user feedback. In response to the findings, specific modifications were made to the design of the icon, ensuring that users can easily locate and access the order status screen after placing their order. This iterative process helps enhance the user experience and ensures that users can navigate the app seamlessly, resulting in a more intuitive and efficient ordering process.
Based on the insights gained from the second usability study, it became evident that users were experiencing frustration during the ordering process. To address this feedback, significant modifications were made to the design. Users were provided with enhanced functionality, including the ability to make changes to their order and undo their actions. Additionally, a clear and intuitive solution was implemented, allowing users to remove their order by simply pressing the "-" or "x" icon on the screen. These design improvements aimed to alleviate user frustration and provide a more seamless and user-friendly ordering experience.
